Bredevoort was being defended by only two companies of (200) soldiers, led by a French captain Gardot Damien and his lieutenant Van Broeckhuysen, because of the absence of Count Hendrik van den Bergh and his supporting troops. Bredevoort was considered impregnable, because the city was surrounded by swamps. Those swamps made it very difficult to get guns within shooting range. Maurice was advancing towards the city with 6,000 troops and 1,200 cavalry which included 13 companies of English troops under Horace Vere. To tackle the swamps Maurice had brought a new invention: a bridge of cork. These bridges were light and mobile and not previously applied. The bridge proved successful and made it possible to get the guns nearby to shoot successfully the walls. Finally, they shot a big breach in the wall so Maurice's troops could storm the city, followed by a very bloody battle, the defenders retreated to the castle. Maurice's soldiers ransacked the town two days long, followed by negotiations to surrender. The defenders were allowed on payment of ransom to leave the city. A soldier of Maurice was in the night looking for loot. He did so by burning a bundle of hay. Carelessness hit the hay loft on fire. The fire hit on to other houses. Eventually burned across the city. Only 20 houses were spared. Citizens fled to the castle, soldiers fled the city. Maurice was very upset about the incident. On the other hand he also thought it was a deterrent for other cities could be.

Following the consolidation of the town, Maurice then went on to take Enschede and this time the city was spared destruction.
